If you have the time take a first aid course. Bet the local community college has one - and the lists for what courses are being offered just came out too (no, not psychic, just also in NC and it's a statewide thing). For that matter, see if any are offered on base freebie like.

I agree with all of the above, have both a book and copy pertinent stuff, but it's best having hands-on training and knowing what to do in the short term without having to look it up.
